World-record slackliner Faith Dickey had to walk from one speeding truck to another across a highline in Volvo Trucks' new ad. Sounds easy? No, there were high winds. Oh, and if she wasn't fast enough, she'd smash into a mountain.

The trucks were taking up both lanes on an unopened highway in Croatia, driving into two tubes of a tunnel. Spoiler alert! Dickey barely makes it in time and isn't crushed to death.
